Sammanfattning
The Swedish economy depends heavily on the construction industry, which has
made a considerable contribution to its expansion and prosperity. The
construction industry has a significant influence on the economy due to its large
workforce and significant investments. The extended duration of the projects
and the requirement for high-quality results within budget limits provide
problems for the construction sector in terms of procurement. Contracts are
essential to ensure the achievement of intended results, and their legal obligation
necessitates a careful approval procedure. It can be difficult to strike a balance
between short-term and long-term goals in the construction industry, which has
an impact on the desire for innovation and resource efficiency.
The aim of this thesis is to address the research questions: How do the project
delivery models design-bid-build (DBB) and design-build (DB) stand against
each other from a quality and end-cost standpoint? By looking specifically into:
1. How do the project delivery models affect the number of total
procurements offers and sub-consultants in the value-chain?
2. Does the number of total procurements offer, and sub-consultants then
effect the result in terms of quality and end cost?
and make recommendations for constructing a roadmap that shows the influence
of various procurement decisions on the results of the project.
The research focuses on assessing the advantages and disadvantages of current
project delivery models and procurement frameworks with the objective to spot
areas for improvement and provide guidance for the roadmap. The research
questions examine alternative models and tactics for procurement and how they
affect Swedish building projects. The research methodology consists of literature
reviews, survey, and interviews with experts from significant construction firms
within the Swedish construction sector. This thesis offers suggestions derived
from the findings and offers insights into the construction industry's
procurement decision-making process.
The thesis also examines a variety of parameters, including accountability, the
quantity of actors engaged, systems of compensation, risk management, methods
II
of evaluation, and stakeholder cooperation. Based on the fluctuating nature of
labour demands, construction businesses tend to depend on subcontractors
rather than keeping a sizable permanent workforce, making risk management
particularly important. Yet, this reliance on contract workers and subcontractors
hinders productivity, restricts opportunities for economies of scale, and lowers
the quality of the production and client satisfaction.
The thesis states that it is challenging to respond to the study question since
procurement procedures are not the main factors influencing bidding, tendering,
and subcontractor stages along the value chain. The conclusion also underlines
how the DBB and DB frameworks differ in the final product's quality, with DB
having a small edge. Furthermore, the DB framework must go through
improvements that emphasize partnered projects and highlight current
standards to become the new standard. It is also advised to use modern digital
applications to enhance customer and contractor communication throughout the
project lifetime. It is advised that future thesis studies investigate how initial
procurement choices affect the aftermarket and property oversight phases of
building projects.
